Altecnic (ZI-301018) Heating Expansion Vessel 18l HV18C

This 18-litre expansion vessel is designed for use in domestic and small commercial heating systems. It manages the thermal expansion of water as systems heat up, helping to maintain stable pressure and reduce the risk of leaks or damage to pipework.

Commonly installed alongside boilers or within plant rooms, this vessel is suitable for closed-loop circuits where consistent system pressure is required. Its size makes it appropriate for modest heating installations where space is limited and capacity needs are moderate.
